Overview
ETE URUACU is a wastewater treatment plant serving Uruaçu, Goiás, Brazil. It serves a population of approximately 19,521 and operates under Brazil's national water quality regulations.
ETE URUACU is a wastewater treatment plant located in the Jardim Campo Formoso neighborhood of Uruaçu, in the state of Goiás, Brazil. The plant serves a population of around 19,521 residents, placing it in the medium-agglomeration category for Brazilian wastewater infrastructure. It is situated in the Central-West region, an area characterized by savanna (Cerrado) biome and seasonal rainfall patterns. Brazil's wastewater treatment standards are governed by CONAMA Resolution 430/2011 and the National Water Resources Policy (Law 9.433/1997). For agglomerations of this scale, secondary treatment is typically required to reduce organic load and suspended solids before discharge. The plant discharges into a local watercourse that ultimately drains into the Tocantins River basin, one of Brazil's major river systems flowing north to the Amazon River delta. The receiving waters support diverse aquatic life and are important for regional agriculture and water supply. Proper treatment helps protect downstream ecosystems and communities from nutrient pollution and pathogens.
Environmental context
The plant's treated effluent enters a tributary of the Tocantins River, which flows northward through the Cerrado and Amazon biomes before reaching the Atlantic Ocean via the Amazon River estuary. The Tocantins basin supports a rich diversity of fish species and is a critical water source for irrigation and human consumption. Effective nutrient removal is essential to prevent eutrophication in downstream reservoirs and maintain water quality for sensitive aquatic habitats.
